|OS: Windows Server 2003|
Exchange ver: 2003
I have multiple servers connected at my home lab. My ISP is Comcast running a dynamic ip address. I have a router with static IP addresses on all servers. I have installed Active directory on my domain controller and the domain name is “lets say ABC.com”
On a separate server I am attempting to set up an exchange server. I purchased ABC.com and own the domain and some hosting. Now when I run a dcdiag to attempt to connect the exchange server I get an errors saying there is no connection with the domain controller. When I ping my FQDN I get the IP address of the internet web site instead of my internal domain name.
Is this because I have my domain name on my network ABC.com? Should I change my domain name to ABC.local? Also if not, how do I differentiate between an internal domain and external web address?
